JOHN E. WARD, OF NEVV' YORK, N. Y., ASSIGNOR TO WARD EQUIPMENT COMPANY,OF

VENTILATOR FOR RAILWAY-CARS.

To all whom it may concern:

Be it known that I, JOHN E. lVAnD, a citizen of the United States,residing in the borough of Manhattan, of the city of New York, in theState of New York, have invented certain new and useful Improvements inVentilators for Railway-Cars, of which the following is a specification,reference being had to the accompanying drawings, forming a part hereof.

This invention relates to the ventilation of railway cars andparticularly to ventilating devices of the general type or character ofthe so-called torpedo ventilator, as applied to the vertical wall of theraised portion of the car roof.

The objects in view, in the construction of ventilators of this type,are the creation of a strong suction or out-draft as the car movesthrough the atmosphere, so as to rapidly draw out the foul air from theinterior of the car and to prevent the entrance into the car,whether inmotion or at rest, of rain, dust, cinders etc.

Continued use of various forms or modifications of ventilators of thistype have brought about the development of the improved form of hoodwhich is the subject of this invention and it has been found that withthis improved form the suctional effect is considerably increased, ascompared with the forms heretofore used, while the cost of manufactureis reduced.

The invention will be more fully explained hereinafter with reference tothe accompanying drawings in which several embodiments of the inventionare illustrated and in which Figure l is a View, partly in section andpartly in elevation, illustrating the application of the improvedventilating hood to a railway car, a portion of the roof of the carbeing shown, together with the inside shutter. Fig. 2 is a view inelevation of the parts shown in Fig. l as seen from the left hand inFig. 1. Fig, 3 is a detail view of the hood in longitudinal section,that is, in a plane transverse to the longitudinal axis of the car, aportion of the car roof being also shown in section. Fig. 4 is a view inside elevation of a modified form of the improved hood. Fig. 5 is a Viewin section on the irregular plane indicated by the line 55 of Fig. 4.Fig. 6 is an underside view of still another modified form, and Fig. 7

is a view in end elevation of the hood shown in Fig. 6.

The improved ventilating hood is intended for application to railwaycars which have the center portion a of the roof raised above the mainportion thereof, and an interposed Vertical wall 0, usually double,shown. Ventilation of the car is effected through the double wall 0, anopening (Z in the inner member of the wall having a movable shutter (Z,and registering, either with or without an interposed sleeve, with anopening (Z in the outer member of the wall.

To the outer member of the wall 0 is secured, in any suitable manner,and so that its interior shall register with the opening (P, theimproved Ventilating hood 6, which is generally triangular in crosssection, as indicated in Figs. 2, 5 and 7, and tapers from its base,which is flanged, as at c, to its rather blunt outer end or nose 6 Thebase of the hood, meaning that end which is applied to the vertical walla, is open and covers or conforms to the ventilating opening (Z2 in thewall. The upper side 6 of the hood is flat and nearly horizontal, havingsuch dip outwardly and also being so rounded off on its edges as tofacilitate the removal of snow, cinders, etc. Its lateral walls econverge downwardly, as clearly shown in Fig. 5, and preferablyterminate in a substantially vertical flange 6 about an opening 6 whichextends from the base of the hood to its outer end or nose.

The features of construction thus far described are common to all theforms shown in the several figures of the drawings. For the purpose ofincreasing the suctional effect of the hood there may be added to thesimpler form of the device, which is shown in Figs. 1, 2 and 3, ribs orflanges 6 on each of the lower, converging sides 6 about the opening 6,such ribs or flanges being inclined downwardly and outwardly from theupper portion of the side 6*, as clearly shown in Fig. at. Such ribs orflanges form chutes or ways in which the air adjacent to the wall of thehood is compelled to travel downward and past the forward flange c andacross the opening a in such manner as to increase the out-draft. Insome cases, also, it may be desirable to increase the area for theoutflow of air from the hood, as by cutting away the nose 6 of the hoodfor a short distance, to form additional opening, as at 0 as indicatedin Fig. 4, and as shown more particularly in Figs. 6 and 7.

Various other additions or changes may be made to meet the requirementsof different conditions of use.

I claim as my invention l A ventilating hood for railway carssubstantially triangular in cross section and tapering from its base toits outer end and having a substantially flat top and an opening in itsunderside between the converging side walls and having also asubstantially vertical depending flange about said opening.

2. A ventilating hood for railway cars tapering from its base to itsouter end and having a substantially flat top and an opening in itsunderside between the converging side walls.

3. A ventilating hood for railway cars tapering from its base to itsouter end and having an opening in its underside between the convergingside walls and having also ribs or flanges on its outer side walls todiroot the air downward and across said openb. o 0 u 4. A ventilatinghood for railway cars substantially triangular 1n cross section andtapering from its base to its outer end and having a substantially flattop and an opening in its underside between the converging side wallsand having on its side walls downwardly and outwardly directed ribs orflanges.

5. A Ventilating hood for railway cars tapering from its base to itsouter end and having an opening in its underside between the convergingside walls and having also an opening in its outer end. I

6. A ventilating hood for railway cars substantially triangular in crosssection and tapering from its base to its outer end and having asubstantially flat top and an opening in its underside between theconverging side walls and its outer end.

7. A ventilating hood for railway ears JOHN E. WARD.
